NO. 853 CAPTAIN PEDRO FAGES TRAIL - In 1772 Fages, commandante at Monterey, vainly looked for a way across San Francisco Bay. With Franciscan missionary Juan Crespí, 14 soldiers, a muleteer, and an Indian servant, he trekked along Carquinez Strait, thence eastward nearly to Antioch before turning back. These, the first white men to explore what became Contra Costa County, passed this point and camped near Danville on March 31, 1772.
